AVClub: They saved the best for last this week, so let’s start there. It turns out there actually is a shark-man on the loose in Central City (presumably DC’s King Shark, who was featured in the comic book prequel The Flash: Season Zero), and his brief appearance here is both startling and hilarious. His first and last words are “Zoom wants you dead,” as he is gunned down by a hooded figure with a techno-weapon. That figure is indeed the Harrison Wells of Earth-2, who reveals himself to Barry just before the end credits roll. It’s a tantalizing cliffhanger, but it’s also frustrating as it only serves to amplify how much this episode ignored the groundwork laid for this season in favor of setting up an entirely different show.
